The mean length of 6 childrens' big finger is 8.3cm. The mean length of 5 adults' big finger is 17.7cm. What is the mean length (rounded to 2 DP) of these 11 people's big finger?
Answer:
The mean for the whole group is 12.57 cm
Step-by-step explanation:
The mean of the length of each group's finger is given by the following formula:
mean = (sum of lengths from each finger)/number of people
Therefore for the first group:
8.3 = (sum1)/6
sum1 = 8.3*6 = 49.8
For the second group:
17.7 = sum2/5
sum2 = 17.7*5 = 88.5
Therefore the mean from the whole group is:
mean = (sum1 + sum2)/11 = (49.8 + 88.5)/11 = 12.57 cm

Answer:
4 : 11
(The 4 is the people that study French)
(The 11 is the people that don't study French. This includes the people that aren't studying a language at all)
Step-by-step explanation:
[tex]\frac{2}{5}[/tex] of the [tex]\frac{2}{3}[/tex] that study a language, is studying French.
[tex]\frac{2}{5}[/tex]*[tex]\frac{2}{3}[/tex]=[tex]\frac{4}{15}[/tex] so [tex]\frac{4}{15}[/tex] of the entire school studies French. that means [tex]\frac{11}{15}[/tex] of the school doesn't study French. In a ratio, it'd be 4 : 11 ratio

Kali is single and earns $45,800 per year. What is her annual federal withholding?
The table would continue this pattern up to 1,800 hours
The question involves creating a table that displays the effect of earned income on government support and total income for a single mother, named Susan. Given that Susan earns $8 per hour and loses $1 in government benefits for every $1 earned, we calculate the impact of different work hours on her total income. The table will illustrate the intersection of labor and welfare economics, showing the disincentive to work that some assistance programs might create due to the reduction in benefits as earned income rises.
To provide an example for Susan's situation: If she works 500 hours at $8 per hour, her earnings from work would be $4,000. With government benefits reducing dollar for dollar, Susan's new benefits would be $16,000 - $4,000, which equals $12,000. So, her total income would be her earnings ($4,000) plus the adjusted government benefits ($12,000), totaling $16,000. The table would continue this pattern up to 1,800 hours
The spinner shown is divided into congruent sections that are labeled 1-6. If the spinner is spun twice, what is the probability of the arrow landing on a 5 and then landing on a 3?
Answer:
1/36
Step-by-step explanation:
This is a simple use of the multiplication rule of probability, which is:
"The probability that Events A and B both occur is equal to the probability that Event A occurs times the probability that Event B occurs, given that A has occurred"
Using this rule, we square 1/6 to get 1/36. In other forms:
Decimal:0.02777777777(Round to whatever decimal place you need)
Percentage: 2.778%(I don't see you needing any more places)

Bonnie had 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills in her pocket. She randomly took 3 bills from her pocket. How much money could Bonnie have taken from her pocket?
Answer:
There are 5 different outcomes, $30, $21, $20, $16 and $11.
Step-by-step explanation:
Bonnie has a total of 6 bills in her pocket. If she takes 3 random bills, this means that there are 20 different possibilities but the five dollar bills and ten dollar bills are not indistinctive so the number is not 20 for this example.
She can take the 1 dollar bill and the two 5 dollar bills which would make 11 dollars.
She can take the 1 dollar bill and the two 10 dollar bills which would make 21 dollars.
She can take the 1 dollar bill, one 5 dollar bill and one 10 dollar bills which would make 16 dollars.
She can take two 5 dollar bills and one 10 dollar bill which would make 20 dollars.
She can take two 10 dollar bills and one 5 dollar bill which would make 30 dollars.
So there are 5 different outcomes, $30, $21, $20, $16 and $11.
I hope this answer helps.
Final answer:
Bonnie could have possibly drawn $11, $21, $20, or $25 by selecting any 3 bills out of 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.
Explanation:
The question concerns the amount of money Bonnie could have taken from her pocket after randomly selecting 3 bills. To answer this, let's consider her initial set of bills: 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.
Here are the possible combinations of 3 bills she could draw:
1 one-dollar bill and 2 five-dollar bills: $1 + $5 + $5 = $11
1 one-dollar bill and 2 ten-dollar bills: $1 + $10 + $10 = $21
2 five-dollar bills and 1 ten-dollar bill: $5 + $5 + $10 = $20
1 five-dollar bill and 2 ten-dollar bills: $5 + $10 + $10 = $25
Therefore, the amounts of money Bonnie could have drawn are $11, $21, $20, and $25.

students at river view middle school are allowed to wear two different colors of uniform shirts. A survey of students at the school shows that a student is three times more likely to wear a red shirt than a white shirt. If a classroom has 24 students, how many students are likely to be wearing red?
Answer:
18 students are likely to be wearing red
Step-by-step explanation:
From the question, we know a student either wears red , or blue, with the probability of a student wearing red is 3 times more probable than wearing white.
So, let’s say out of the 24 students, x of them are wearing white. What this practically mean is that 3 * x = 3x of the students would be expected to be wearing red.
Now, adding the number of people wearing red and white together in terms of x, we have x + 3x = 4x
We equate this to 24; 4x = 24 and x = 24/4; x = 6
The number wearing red probably is 3 * x = 3 * 6 = 18 people
To determine how many of the 24 students likely wear a red shirt, given red is three times more probable than white, we calculate that 18 students are likely wearing red shirts.
The question asks us to determine how many students in a class of 24 are likely to be wearing a red shirt if students at River View Middle School are three times more likely to wear a red shirt than a white shirt. To solve this, let's define the number of students wearing a white shirt as x. Since a red shirt is three times more likely, the number of students wearing a red shirt would be 3x. The total number of students in the classroom is the sum of those wearing red and white shirts, which is x + 3x = 24. Combining like terms, we get 4x = 24. Dividing both sides by 4, x equals 6. This means 6 students are wearing white shirts. To find the number of students wearing red shirts, we multiply the number of white-shirted students by 3: 3 times 6 = 18. So, 18 students are likely to be wearing red shirts.

1/4 inch cubes were used to fill a prism. The dimensions of the prism are 1.5 inches x 1 inch x 3.75 inches. How many 1/4 inch cubes can fit into the prism?
A) 22.5
B) 360
C) 720
D) 180
Answer:
B) 360 cubes
Step-by-step explanation:
We can start by finding how many cubes fit into the length of the prism (1.5 in) which is 6 cubes for 1.5 in/ 0.25 in = 6.
Then we can find the number of cubes to fit the width of the prism (1 in) which is 4 cubes for 1 in/ 0.25 in = 4.
Finally we find that 15 cubes fit the height (3.75 in) for 3.75 in/ 0.25 in = 15 cubes.
Multiplying the together, we get 6*4*15=360 or B

The sales tax rate on a new vehicle is 6%. If the vehicle is $8,000, then how much will be charged for sales tax?
The sales tax charged on a $8,000 vehicle would be $480.
What is a percentage?The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying it by 100.
The percentage change is also calculated using the same method.
In percentage change we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
The sales tax rate is 6%, which means for every dollar spent on the vehicle, 6 cents will be charged for sales tax.
To find the amount of sales tax charged on $8,000 vehicle, we can multiply the price of the vehicle by the sales tax rate as a decimal.
Sales tax = $8,000 x 0.06
Sales tax = $480
Therefore,
The sales tax charged on a $8,000 vehicle would be $480.

3. A flower bed has 26 rows of flowers and
each row has 8 flowers. One section of the
flower bed contains red flowers. There are
8 rows of red flowers. The rest of the flower
bed is white flowers. How many white
flowers are there?
To find the number of white flowers, we subtract the total number of red flowers (64) from the total number of flowers (208), resulting in 144 white flowers.
The student's question involves calculating the number of white flowers in a flower bed given the total number of flowers and the number of rows of red flowers.
There are 26 rows of flowers in total, and each row contains 8 flowers. If 8 rows consist of red flowers, we can calculate the number of white flowers by subtracting the red flowers from the total number of flowers.
Here are the steps we'll take to solve the problem:
Multiply the total number of rows by the number of flowers per row to find the total number of flowers.
Total flowers = 26 rows * 8 flowers/row = 208 flowers
Multiply the number of rows of red flowers by the number of flowers per row to find the total number of red flowers.
Total red flowers = 8 rows * 8 flowers/row = 64 flowers
Subtract the number of red flowers from the total number of flowers to find the number of white flowers.
Total white flowers = Total flowers - Total red flowers = 208 flowers - 64 flowers = 144 white flowers.

In trigonometry, both sine and cosine are negative in the third quadrant of the coordinate plane, as both the x and y coordinates are negative in this quadrant.
Explanation:In the context of trigonometry, on the coordinate plane, sine and cosine are both negative in the third quadrant. The sine function represents the y-coordinate and the cosine function represents the x-coordinate of a point on the unit circle. Hence, in the third quadrant, where both x and y are negative, both sine and cosine are negative as well. This is a basic idea from trigonometry and is commonly referred to as the rule 'All Students Take Calculus', which helps to remember the sign of sine, cosine and tangent in each quadrant. A- all (Quadrant I, all are positive), S - Sine (Quadrant II, only sine is positive), T - Tangent (Quadrant III, only tangent is positive), C - Cosine (Quadrant IV, only cosine is positive). Therefore in the III quadrant, both sine and cosine are negative as only tangent (ratio of sine to cosine) is positive.
